# We need to know two things in the response of a persistence call:
#
# * The model we just tried to persist
# * Was the persistence successful?
#
# This object wraps those bits of data. The call is considered
# unsuccessful when it adheres to the ActiveModel#errors interface,
# and #errors is not blank. In other words, it is not successful if
# there were validation errors.
#
# @attr_reader object the object we are saving
class JsonapiCompliable::Util::ValidationResponse
attr_reader :object
# @param object the model instance we tried to save
# @param deserialized_params see Base#deserialized_params
def initialize(object, deserialized_params)
@object = object
@deserialized_params = deserialized_params
end
# Check to ensure no validation errors.
# @return [Boolean] did the persistence call succeed?
def success?
all_valid?(object, @deserialized_params.relationships)
end
# @return [Array] the object and success state
